You still might have problems, and you shouldn't use someone else's
domain name! I can't emphasise that enough. You could find a cheap
registrar, and get your own. You could use one of the domains that are
set up for this sort of thing (test, localhost, as I did with
my .localhost examples).

(I'm replying quickly now, I don't have much spare time, I'll reply in
more depth later on.)

I'd chmod to rwx------, though the timeout errors are something else.

Is your DNS server configured to allow other local clients to query it?
Likewise, with firewalling (does it allow them through).

Make some changes, like this, put the serial number *inside* the
brackets, not before it:

nine.homelinux.com. IN SOA homer.nine.homelinux.com. (
        1123345344 ; serial
        10802 ; refresh
        3600 ; retry
        604800 ; expire
        38400 ; ttl
        )

You shouldn't need the whole filepath to the zone file, if you're
putting it in the same directory as it expects to find zone files (the
same as the other zone files).

I think you'll need to insert this somewhere into the named.conf file:

        include "/etc/rndc.key";
        
Post us your current /etc/dhcpd.conf file here, too. (If you've since
modified it.)
